INVENTOR JOHN F. EYRING ATTORNEY Patented June 1, 1954 UNITED STATES PATENT OFFICE 9 Claims.

1 This invention relates to certain improvements in bathing apparatus with particular reference to a novel construction of bath tub and the like,

whereby obvious objections to tub bathing are therewith adjacent parallel conduits or passageways adapted to receive water from a controlled source to selectively direct said water into the proper conduits or passageways according to the type of bath and operational function desired.

A further object is to provide a device of the type indicated that will be practical, both from the standpoint of construction and use, and one that can be manufactured by conventional methods With little or no additional cost.

A still furtherobject is the production of a tub construction provided with an overflow gutter extending substantially around the whole upper part of the tub at a height to receive and carry off all of the soiled or unclean water from the surface of the water in the tub during a bathing period, means being provided to maintain a regulated, constant flow of water into said tub during the entire bathing operation.

It is a further object to use this gutter as a flush rim or means for washing down the sides of the tub after a bath, means being provided for directing clean Water into said gutter for this purpose after the tub has been drained through the conventional drain in the bottom of the tub. This flushing water will also maintain the gutter in a clean and-sanitary condition, saidgutter at the low end being provided with a drain opening for removing any sediment or soiled water not flushed over the edge of said gutter. It is of course to be understood that this gutter drain is also functioning while the gutter is receiving the overflow from the tub during the bathing operation.

A still further object of the invention is to combine with the other features hereinbefore mentioned, a rim shower so that the bather may, if desired, by manipulating the proper valve,

obtain a rinse or'washdown after his tub bath.

The preferred embodiment-of the invention is 2 illustrated in the accompanying drawings in which:

Figure 1 is atopplan view of the improved tub.

Figure 2 is a longitudinal vertical sectional view thereof.

Figure 3 is a transverse-sectional view on line 3-3 ofFigure 1.

Figure 4 is a transverse vertical sectional view on line 4- of Figure 1.

Figure 5 is an enlarged partial vertical sectional View on line 5-5 of Figure 1, showing'in detail the supplemental water discharge chamher and the adjoining ends of the overflow gutter and its parallel flushing conduit, together with the Water supply piping therefor.

Figure 6 Ban enlarged detail sectional view on line 6-8 of Figure 1, showing a transverse section of said water discharge chamber.

Figure '7 is an enlarged detail transverse sectional view on line 1-4 of Figure 1 more clearly showing the various passageways comprising the overflow gutter, the water supply conduit for flushing said gutter, and the shower spray conduit, all formed as an integral casting with the tub; and

Figure 8 is a perspective view of one end of the tub more clearly showing the relationship of the various parts of the tub proper.

Referring to the drawings in detail, and with particular reference to Figures 2, 7 and 8, the improved tub l is preferably made as a casting having formed integrally with the upper surrounding rim-portion, adjaoent parallel passageways or conduits consisting of a gutter 2, a-water supply conduit 3 for flushing said gutter, and a water supply conduit 4 for the shower spray.

The gutter 2 is provided with a drain-connection 5 and the tub is provided with the usual bottom drain 8. The main water supply-for filling the tub is the usual mixing faucet l.

The gutter 2 and the water conduits 3 and 4 extend completely around the tub except at one end where there is interposed a supplemental water discharge chamber 8 (see particularly Figs. 4, 5 and 8), the lower edge of said chamber *8 being on the same level or horizontal plane with the upper edge of the overflow rim 9- 0f the gutter 2.

For the purpose of flushing the gutter 2 for cleaning purposes, the conduit 3 is provided with spaced bottom openings 10 extending around the tub, the complete length of said conduit 3.

Formed in the inner side wall of the conduit '4 are inwardly directed spacedopenings II also extending around the upper edge of the tub I,

sageways extending around the upper providing a shower spray as desired when water is supplied to said channel 4.

These various passageways, conduits, chambers and the like, may be supplied with water in any conventional manner provided the water supply is selectively controlled according to the operation or function desired.

One form af piping is illustrated in Figure wherein a main hot and cold water pipe [2 is provided with branch pipes l3 and M for furnishing water to the supplemental water discharge chamber 8 and to each opposite end of the gutter 2 respectively, whereby during the continuous supply of water to the chamber 8 a certain amount of water will be simultaneously directed into the gutter 2 to provide a movement or circulation of water along the gutter to the gutter drain 5 as the water in the tub overflows into said gutter during a tub bath, in a manner and for the purpose to be hereinafter more fully described.

This supply pipe |2 may be provided with a conventional mixing valve (not shown) to obtain proper water temperature for the bath.

The flushdown conduit 3 is supplied with water through a pipe l5 and the shower spray conduit 4 is supplied through a pipe I6, said pipes l5 and I6 being provided with the necessary control valves (not shown), whereby all of the water supply pipes l2, I5 and It will be capable of selective control, either singularly or in combination according to the type of bath desired and the proper function to be performed.

In using the tub, the same is filled through the usual faucet l until the water level has reached the top of the overflow rim 9 of the gutter 2, whereupon this faucet is closed and a limited amount of water is continuously supplied to the tub through the supplemental water discharge chamber 8 by way of pipes 12 and I3, just sufficient to maintain a steady overflow of the soiled surface water into the gutter 2 during the bath, where it is carried along and discharged to the waste through the drain 5.

At the same time water is being admitted to the chamber 8, a relatively smaller amount of water is admitted into the opposite ends of the gutter 2 by way of pipes M for the purpose of creating a circulation of the overflow water towards the gutter drain 5.

After the tub bath, the water supply through the pipes l3 and I4 is shut off and the tub drained through the main drain 6.

If a washdown shower is now desired to complete the bath, water is admitted through pipe [6 into the channel 4 and out through the spray openings II.

The final operation, after shutting off the water to the spray shower pipe 16, is a flushing of the gutter 2 and a washdown of the sides of the tub which is accomplished by opening the valve to water pipe I5, whereby the water will be directed into the gutter through the top openings It for flushing the same and will flow down the sides of the tub in an obvious manner and carry all dirt and sediment out through the gutter drain 5 and the main drain 6.

It is to be understood that applicant is not to be limited to the specific features as shown and described herein, as slight changes may be made without departing from the spirit of the invention as covered in the appended claims.
